T alla/)hom it may concern: n Y Beit knownthat I, GEQRGE W; HEATH, a citizen of,;the United States of'y America, re-

siding at East Orange, Essex County, Stater of New Jersey, have f invented certain. new

and l.useful Improvements in Pencils, of which the following is a specification.

This invention relates to improvements in magazine pencils, one of the objects being to,

provide means whereby the nozzle end of the pencil, or end which projects r4beyond the end of the casing, when the pencil is in use, can

be rigidly supported beyond the end of;l the casing, said rigid support being providedby means operable by the movement of the nozzle as it is projected forwardly. When the nozzle is retracted, the supportingmeans.

will be operated to remove pressure from the nozzle so that said nozzle can be easily moved.

A further object of my invention is to provide an improved magazine for extra leads anda closure therefor which is not normally removable from the pencil as a Whole, but ment which operates the devicegffor projecting and retracting the lead carrier, said closure actingy tol prevent the spare leads'. from dropping out of the magazine, en masse,

casing. The foregoing is a mere outline of my invention, a more detailed description of which will follow.

I will now proceedto describe my invenwill point out in theappended claims, reference being had totheaccompanying drawin Wherein:- n

Figure 8 is an enlarged view of the lead 'carrier and its operating parts, some of which are broken `away to disclose other parts Onegof the objects ofmyI invention is yto provide means to impart rigidity to the leadcarrier of a magazine pencil when itis .extended, in order that there will not be any looseness on the part of ythe lead-carrier While Writing with the` encil. To accomplish this result, I vprovides a device which is arranged to clamp the lead-carrier, when it is extended, theclamping action being effected automatically during the movement of the lead-carrier from tlieretracted to the extended position, but the lead carrier will not be clamped until kfully extended. To illustrate my invention, I have selected a magazine pencil comprised of a carrier 8 for the lead 9. The carrier 8 is provided with a pin 10 operating ini a slot 11 extending longitudinally of a sleeve 12.A The pin and slot act to ykeep the lead-carrier from rotating. The pin 10 extends through said slot and engages aehelicalslot 13`in a sleeve 14 carried by sleeve 12. The sleeve 14 carries a ri id` pin14,isee Fig. ,8, to engage a helical s ot 15 in a sleeve lcarriedby 'sleeve 14. Over dered, as at 20, to a collar21 xedly carried p k5, the lead-carrier will be extended as in catedin Fi 2'.k kWhen said sleeve 17 is pushedin, t .ey lead-carrier `will be retractedr as indicated in Fig. 4; .The movement of sleeve 17 operates the sleeve 16, having the helical slot 15, rlongitudinally of the pencil, which action rotates Sleeve 14-having helical slot 1.3 for the reason that the pin carried by sleeve 14 en ages the slot 15 and in traveling therethroug i is. revolved, thus revolving sleeve 14. llfhen sleeve 14 is rotated, the lead carrier 53 will be moved longitudinally of the pencil due to the fact that the pin attached thereto, will be carried alonel slot to provide yieldable fingers26 arranged passes.

to clamp or engage the` carrier 8. To coopcrate with the clamp, I rovide the sleeve 12 with a. tubular head 2 having a conical end 28 through which the lead carrier 8 The clamp 24 operateswithin kthe head27. The conical end of the head 27 .fits the conical end 29 of the casing 23. It will be seen that the carrier 8 is reduced in diameter to provide t in this instance) a shoulder 30; the extent of the reduced portion 31a of the carrier will be approximately equal to the. extent of longitudinal movement of said carrier. y

'When the lead carrier 8 is 'pm 'eCted forwardly. by pulling sleeve 17 outwardly, the collet or clamp 26 will move toward the conical end 28 of the tubular head 27. It may here be stated that the collet or clamp will snugly fit the reduced portion of the lead carrier; hence, will move with it. lVhen the collet or clamp 24 reaches the conical end of the head 27, it will slip upon the carrier until shoulder 30 is forced against same, which action will take place just prior to the completion of the outward stroke of thge carrier. During the completion of the outward strokeof the carrier, the clamp 24 will be forced into the conical end of the head 27, as'indicated in Fig. 2, thereby forcing fingers 26 firmly int-o contact with the carrier, after which the. carrier will be rigidlyk supported, as there will not be any lost motion between it and the casing 23. Then the lead carrier is retracted, the clamp 24 will be drawn outv of the conical end of the head 27.

A. further object of my invention isto provide an improved form of magazine for sparc leads. To this end I provide the outer sleeve. 18, which carries the flange '22, -at one end with a head member 31 carrying lugs 32, in this instance four, each lug being connected to the flange 22 by'a rod 33, said rods dividing the space 34, between casing 23 rand sleeve 18, into four compartments 35. The open end of the casing-23 is closed by a cap 36 having threads 37 to engage the interrupted threads 38 on the Lhead member 31. The threads 38 are interrupted' or cut away'at 39 in alinement with the compartments 35 in order that the spare leads 40 can move freely out of the compartments. The cap 3,6 is counterbored slightly at 41 to provide a Harige 42 for the outer end of the leads to rest upon when the pencil is inclined, as indicated in Fig. 5. It will be obvious that the leads will be engaged at both ends, one endbeing located in the annular groove formed by the counterbore `4l. the other end being supported by the head member- 31. By this means less breakage of leads willoccur, also loss by dropping out of the'magazine. The rods 33 prevent the leads rfrom becoming jammed in the magazine by rbeing turned too much at an angle relative to the axis ofthe. pencil: 'in other words, said rods maintain the leads in plane substantially parallel with the axis of the pencil. The cap is slidaiile lougi `tudinally of the sleeve 17 and is held against removal therefrom by a plug 43 tilted in the outer end of sleeve 17, the diameter of the plug being slightly more than the sleeve 17; hence, a stop will be prox ided to prevent the cap 36 from morinir oli' the sleeve 1T. The rods 33 at one end engage the collar and at the otherend they engage the lugs 32 on head 31. fi/bile the'cap 36 is being un- Screwecl. the rods 33 will prevent the leads from being forced circumferentially around the sleeve 18 and brol'gen. It will be apparent that the cap 3G is movable longitudinallyalong with the sleeve 17 while it en# gages the end plug 43 and draws the sleeve outward there-with for operating the lead carrier Land itis Varranged "to uncover the open end of the magazine independently of the. sleeve l?, but the cap 36 cannot be removed from the said sleeve 17. 'In short, the sleeve 17 can be operated to actuate the lead can rier withoutremoving the cap from the casing, as said sleeve is slidable in saidTL cap.

Referring again to the action of the colletl or clamp 24, it is apparent that said collett will be forced between the carrier 8 and abutment or inclined surface 28 when `said carrier extended to its full extent; hence, 1n

said carrier will be movement.
